AP Chemistry — Atomic Structure and Properties

Atomic Structure and Properties is the first of 9 units in the College Board's current AP ChemistryCourse & Exam Description. It opens the course and sets up Molecular and Ionic Compound Structure and Properties.

Our Atomic Structure and Properties set has 12 practice questions, each with a written explanation, a one-line key takeaway, and a rationale for every wrong choice — so you learn why the right answer is right and why each distractor is tempting. You can work them as a timed set or read the worked solutions straight through.
